Captive vs Group-Captive vs OA-PPA

Three structures. Same idea — cheaper, cleaner power than the grid.

Captive (you own)

You hold ≥26% equity & consume ≥51% of generation. Lowest cost, full depreciation benefit, no cross-subsidy surcharge.

Group-Captive

Multiple consumers jointly own the plant proportionally. Best for industry clusters or sister concerns sharing one large plant.

Open-Access PPA

Zero capex. We own the plant & sell you power via grid-wheeling at a locked tariff 25–35% below DISCOM. Off-balance-sheet.

Why Vermson

Captive solar is half engineering, half paperwork. We do both.

SPV & legal structuring

We structure the captive SPV, equity holding and PPA so you stay compliant with the Electricity Rules and Captive Generation criteria.

Wheeling expertise

Open-access applications, transmission tie-ins, cross-state wheeling — we have a track record of getting them approved without re-filings.

Full lifecycle ownership

EPC + O&M + 25-year PR guarantee. We don't hand off operations after install — we own performance for the life of the plant.

Answers to the questions we hear most. Have a different one? Drop us a message and we'll write you back.

01.What qualifies as a "captive" plant?

Under the Electricity Rules, a captive plant requires the consumer (or group of consumers) to hold ≥26% equity in the SPV and consume ≥51% of the generated power. Captive status exempts you from cross-subsidy surcharge and additional surcharge — biggest tariff benefit available.

Both. Intra-state wheeling is straightforward; inter-state wheeling needs additional approvals from CTUIL / RPC and a separate inter-state transmission application. We've executed both — typically inter-state takes 3–4 months longer to commission.

Captive: you own ≥26%, get full depreciation, lowest lifetime cost, but it's on your balance sheet. Open-access PPA: we own the plant, you buy power via grid-wheeling at a locked tariff — zero capex, off-balance-sheet, slightly higher per-unit cost. We model both for your CFO before you decide.

8–12 months end-to-end: 2–3 months for land + SPV + approvals, 4–6 months for civil & installation, 1–2 months for transmission tie-in & commissioning. We run land identification and regulatory filings in parallel with engineering to compress the timeline.
